Virtual Machine (VM)

A virtual machine (VM) is a software emulation of a physical computer. On one computer you can create several VMs that will use its computing resources (processor, adapter, etc.), but work in isolation and independently of each other. Virtual machines are actively used in cloud computing and data centers.

Types of hypervisors for VM deployment

VMs are deployed using a hypervisor that allocates host machine resources to each virtual machine. There are two types of hypervisors.

The first type of hypervisor. Running directly on the host hardware, they are often used in enterprises. Examples include Hyper-V from Microsoft and ESXi from VMware. Hypervisors of the first type.

The second type of hypervisor. Run on the host operating system and are often used for personal or development purposes. Examples include VMware Workstation and Oracle’s VirtualBox.

Benefits of virtual machines

Efficiency. VMs allow for better utilization of hardware resources because multiple virtual machines can run on a single physical machine.

Flexibility. VMs can be easily created, modified, and deleted based on business needs.

Isolation. VMs are isolated from each other, which increases information security and minimizes threats and vulnerabilities.

Ease of management. Virtual machines are easy to manage. You can create or delete VMs with a few clicks in a special panel..
